The value of surface tension of isopropyl alcohol is?

Explanation

Surface tension depends mainly upon the forces of attraction between the particles within the given liquid and also upon the gas, solid, or liquid in contact with it. The stronger the intermolecular interactions, the greater the surface tension. To answer this question, you have to compare the intermolecular forces between the molecules by comparing their structures. Structure of isopropyl alcohol: since it has 1 OH group, it can form 1 hydrogen bond maximum. Structure of water: water can form 4 hydrogen bonds maximum. Structure of ethylene glycol: ethylene glycol has 2 OH groups, so it can form 2 Hydrogen bonds at maximum. It also has less wander vaal forces than isopropyl alcohol due to its lesser size and Mr. Structure of Methyl Alcohol: It can form 1 Hydrogen bond at maximum like isopropyl alcohol but has less Vander waal forces than isopropyl alcohol as it has a small size and less Mr so will have more surface tension.
